We're told it's not merely 'sales'. No, it's an art. "The art of selling". And with over 4 million hits on Google, you could easily argue that the art of selling is more popular than painting.

The same goes for the two sub-categories of cross-selling and up-selling. They're arts as well, you know. Mystic and creative disciplines...

The security of 3G and GSM mobile phone calls has been questioned recently.

Apps (defined as games, information services, social networking video and web content among other things) dominated MWC10 with debate focused on the provision of radio network capacity to support them, the technologies used to create them and the methods for Mobile Network Operators (MNOs) to monetise them. Given the fragmentation in technology and the investment needed from MNOs to provide capacity coupled with a lack of reward for MNOs, we would be forgiven for thinking the App as we know it is not long for this world. However new technologies offering broader platform support, plus smart network investment coupled with new business models, mean the App will evolve and come of age ready for 2011.

I’ve previously talked about a report from 2009 which warned how touch-screen phones that weren’t true smartphones were pushing down ARPU. Consumers thought they were buying something that was relatively advanced but were being seduced by form over function.

This week HTC stepped in to the arena with the HTC Smart, described by HTC's Peter Chou as "a more-affordable smartphone". Although it may not fit everyone’s definition of a smartphone, it certainly ticks most of the boxes. It has an open operating system, Qualcomm’s Brew platform, which has over 18,000 available applications and has been installed on over 1200 handset models worldwide.
